When I issue "sublime.log_input(True)" and "sublime.log_command(True)" in the console, I can see key and command events for other keys and shortcuts, but those listed above do not fire, either for input or command. If I map the commands to other keys (like 'ctrl+shift+;') they start working.

This same thing is happening to me. At first, it was CMD-SHIFT-P for Command Palette that stopped working. That persisted regardless of restart, and lasted for a few days. Now, I suddenly can't save with CMD-S, either. Save from the File menu works fine. CMD-S works fine in every other application.

I'm on 10.8.5, with Sublime build 3047. Any ideas? Can I supply logs or anything useful?
